Futurabond U – dual-cure universal adhesive in single dose delivery system

Futurabond U
Futurabond U is a dental adhesive for use with methacrylate-based restorative, core build-up or luting materials.

It can be applied with phosphoric acid etching (selective enamel etching or totaletch) of the dental hard tissue as well as without (self-etch).

Futurabond U contains organic acids, (di)methacrylates, amines (DABE) and BHT.

Futurabond U should not be used in case of known hypersensitivities (allergies) to any of these ingredients.

Indications:

  • [A1]  Adhesive for direct restorations of all classes of cavities using light-curing composite/compomer/Ormocer materials with a methacrylate base.
  • [A2] Adhesive for core build-ups made of light-curing composite materials.
  • [A3] Adhesive for indirect restorations with light-curing luting composites.
  • [B] Intraoral repair of composite, compomer or Ormocer restorations, ceramic veneers and allceramic restorations without an additional primer.
  • [C] Treatment of hypersensitive tooth necks.
  • [D] Protective varnish for glass ionomer cement restorations.
  • [E1] Sealing of cavities prior to amalgam restorations.
  • [E2] Sealing of cavities and core preparations prior to the temporary luting of indirect restorations.
  • [F1] Adhesive for direct self-curing or dual-curing composite restorations of all classes of cavities and for core build-ups.
  • [F2] Adhesive for indirect restorations using dual-curing or self-curing luting composites.
  • [G] Luting of root posts with dual-curing or self-curing luting composites.

Instructions for use  Futurabond U

Futurabond U not only ensures a secure bond to natural dental hard tissue, but also to composites, metals and ceramics. It is necessary to isolate the working field from moisture. Any contamination of the cavity or material surface with blood or saliva must be prevented. The use of a rubber dam is recommended.

The subsequent stages of application depend on the indication (see sections [A] – [G])

[A] Direct or indirect restorations with light-curing restorative, core build-up or luting composites

  1. Prepare the cavity and core according to the principles of the adhesive restoration technique, and remove any plaque or tartar in the case of noncarious class V cavities. Clean with water. Dry off excess water with a gentle stream of air. Do not overdry the dentin. The objective is a surface with a silky matt appearance. Protect areas near to the pulp with a suitable cavity lining based on calcium hydroxide.
  2. Etching of the dental hard tissue (optional)
    In self-etch mode, Futurabond U achieves high levels of adhesive strength on enamel and dentin. Prior etching of the dental hard tissue may optionally be carried out. Only enamel which is unprepared must always be etched at the beginning of the bonding process.
    – Etch the surfaces to be etched using a dental acid-etch agent based on phosphoric acid (see applicable instructions for use).
    – Aspirate the acid-etch agent, rinse with water for approx. 20 s. Dry off excess moisture with a gentle stream of air. Do not overdry the dentin. The objective is a surface with a silky matt appearance.
  3. Activating Futurabond U SingleDose:
    Detach a SingleDose blister at the perforation and turn the printed side up. Hold the SingleDose blister between thumb and forefinger and, by pressing on the area marked “press here”, allow the liquid contained in the blister to flow into the mixing and dispensing chamber. Position the enclosed Single Tim applicator in the center of the colored circle in order to pierce through the foil of the mixing and dispensing chamber. Expand the opening to its maximum size using a circular motion. By stirring thoroughly with the applicator, create a homogeneous, streak-free mixture of the two liquids.
  4. Apply the adhesive homogeneously to all cavity surfaces and rub in for 20 s using the Single Tim.
  5. Dry off the adhesive layer with dry, oil-free air for at least 5 s in order to remove any solvents.
  6. Cure the adhesive layer for 10 s using a commercially available polymerization device (LED or halogen light with an output of > 500 mW/ cm²).
  7. Apply the restorative, core build-up or luting material in accordance with the respective instructions for use.

FUTURABOND U

[B] Intraoral repair of fillings or restorations (made from composite, glass ceramic, zirconium oxide ceramic, aluminum oxide ceramic, metal (incl. amalgam))

  1. Thoroughly roughen the surface of the restoration to which the adhesive is to be applied and sandblast it, preferably with aluminum oxide < 50 µm. In the case of ceramics, remove the varnish 1 mm beyond the margin.
  2. Clean thoroughly with water spray and dry with moisture- and oil-free air.
  3. Continue with the application of Futurabond U immediately afterwards (see [A] 3.-6.). The use of an additional primer is not necessary.
  4. Carry out the repair using a light-curing composite according to the manufacturer’s instructions for use.

[C] Treatment of hypersensitive tooth necks

  1. Clean the tooth neck in the usual way (e.g. with polishing paste or using a powder jet).
  2. Clean thoroughly with water spray and dry with moisture- and oil-free air. Do not overdry. The objective is a surface with a silky matte appearance.
  3. Afterwards, continue with the application of Futurabond U (see [A] 3.-6.).
  4. The oxygen inhibition layer should be removed using a cloth or a foam pellet.

[D] Protective varnish for glass ionomer cement restorations

  1. If a matrix was used to facilitate shaping, remove the matrix first.
  2. Activate Futurabond U SingleDose (see [A] 3.).
  3. Apply Futurabond U to the finished modelled restoration using the Single Tim.
  4. Dry off Futurabond U with dry, oil-free air for at least 5 s in order to remove any solvents.
  5. Cure Futurabond U on every surface of the restoration using a commercially available polymerization device for 10 s (LED or light with an output of > 500 mW/ cm²).
  6. Once the restoration has completely cured, grind the occlusion and seal the ground areas once more using Futurabond U in order to prevent the restoration from drying out.
  7. The oxygen inhibition layer should be removed using a cloth or a foam pellet.

[E] Sealing of cavities prior to amalgam restorations or prior to temporary luting
Note: Do not seal cavities with Futurabond U if temporary luting using a methacrylate-based material is scheduled afterwards.

  1. Prepare the cavity according to the further treatment planned. Clean with water. Dry off excess water with a gentle stream of air. Do not overdry the dentin. The objective is a surface with a silky matt appearance. Protect areas near to the pulp with a suitable cavity lining based on calcium hydroxide.
  2. Activate Futurabond U SingleDose (see [A] 3.).
  3. Apply Futurabond U to the cavity surface to be treated using the Single Tim and rub in for 20 s.
  4. Dry off Futurabond U with dry, oil-free air for at least 5 s in order to remove any solvents.
  5. Cure Futurabond U using a commercially available polymerization device for 10 s (LED or halogen light with an output of > 500 mW/ cm²).
  6. Depending on the indication, continue to work with the desired material afterwards in accordance with the corresponding instructions for use.

[F] Direct or indirect restorations with self- or dual-curing restorative, core build-up or luting composites

  1. Prepare the cavity or core according to the principles of the adhesive restoration technique. Clean with water. Dry off excess water with a gentle stream of air. Do not overdry the dentin. The objective is a surface with a silky matte appearance. Protect areas near to the pulp with a suitable cavity lining based on calcium hydroxide.
  2. Etching of the dental hard tissue (optional)
    In the self-etch mode, Futurabond U achieves high levels of adhesive strength on enamel and dentin. Prior etching of the dental hard tissue may optionally be carried out. Only enamel which is unprepared must always be etched at the beginning of the bonding process (e.g. in the luting of Maryland bridges).
    – Etch the surfaces to be etched using a dental acid-etch agent based on phosphoric acid (see applicable instructions for use).
    – Aspirate the acid-etch agent, rinse with water for approx. 20 s. Dry off excess moisture with a gentle stream of air. Do not overdry the dentin. The objective is a surface with a silky matte appearance.
  3. Afterwards, continue with the application of Futurabond U (see [A] 3.-6.).
  4. Depending on the indication, continue to work with the desired material in accordance with the corresponding instructions for use.

[G] Luting of root posts

  1. Activate Futurabond U SingleDose (see [A] 3.).
  2. Rub the mixed adhesive into the tooth core surfaces to be bonded for 20 s using the Single Tim. Using a suitable disposable applicator (e.g. Endo Tim), extract further adhesive from the same blister of SingleDose and rub it into the root canal for 20 s.
  3. Dry off the adhesive layer with dry, oil-free air for at least 5 s in order to remove any solvents. Remove any excess material by dabbing with an absorbent paper strip. Do not light-cure the adhesive layer.
  4. Insert the root post, which has been prepared in accordance with the manufacturer’s instructions, into the root canal using a suitable self- or dualcuring composite for post luting (see applicable instructions for use) in such a way that a slight excess of material is achieved.
  5. To fix the root post and cure the occlusally-applied Futurabond U, the material should be light-cured for 40 s.

Warnings / precautionary measures:
– The Futurabond U SingleDose blister must not be bent or folded prior to activation. Should the blister exhibit apparent signs of damage such as folds or kinks, it must no longer be used.
– The foil of the blister and the label must not be damaged by the fingernails on the upper surface nor underneath.
– No tools must be used in the activation. Only the thumb and forefinger may be used for activation, whereby the thumb must be placed exactly on the marking of the label and the forefinger directly on the opposing underside.
– Do not carry out the activation or the subsequent piercing with the Single Tim near to the eyes.
– Never press on both depressions at the same time or push the liquid to and fro between the depressions.
– Phenolic substances (e.g. temporary materials containing eugenol) impair polymerization and therefore must not come into contact with Futurabond U.
– Avoid contact with the oral mucosa. Contact with Futurabond U may cause whitening of the oral mucosa as a result of the coagulation of proteins. This is a reversible effect which subsides within a few days.
– In case of eye contact with Futurabond U, rinse eyes immediately with plenty of water and seek medical advice.
– Once it is activated, Futurabond U is self-curing and light-curing and further processing must therefore take place immediately. Avoid intense lighting during application.

Storage:

Store at temperatures of 39 °F to 73 °F (4 °C to 23 °C). Do not expose to direct sunlight or the operating light. Do not use the product after its expiration date.
